MAFS.912.G-SRT.1.1

MAFS.912.G-SQR.1.1 - Know the properties of dilations given by a center and a scale factor. 

• A dilation taking a line not passing through the center of the dilation to a parallel line and leaves a line passing through the center unchanged.
• The dilation of a line segment is longer or shorter in the ratio given by the scale factor.

1. The benchmark will be assessed using Equation Response, Multi-select, Graphic Response, Open Response, Selectable Text, or Simulation Response.
2. Items may use line segments of a geometric figure.
3. Items will give the center of dilation and the scale factor.
4. Items may give the student a figure or its dilation, center, and scale and then ask the student to verify the properties of dilation.
